To all whomit may concern:

Be it known that I, JULIUS an resident of St. Joseph, Berrien county, ll lu'higan, have invented a certain new and useful Improvement in Box-Blank Machines, of which the following is a specifi- -cation.

My invention relates to box-blank maholder comprises one or more endless linkbelts. In machines Of-this character, and owing to lost motion, uneven feed, or other reasons, it sometimes happens that the continned operation of the machine for some "time. results, in bringing the work-holder ner that the staples will always be driven in the proper places in the blanks.

- Broadly considered, therefore, the object of my invention is to insure against driving of the staples at points where they are not desired or needed.

More specifically considered, the object of my invention is to provide means controlled by the traveling motion of the work for antomatically stopping the driving of staples,

while stapled and unstapled blank materials are on the machi'ne, behind and in front of the staplers, for any desired purpose, but more particularly with reference to the operation of th machine in such manner as to prevent the rivingof staples in any gaps or spaces necessarily left in the work from time to time, and generally appearing at regular intervals therein.

In the accompanying drawings, Figure l is a plan of a machine embodying the principles of my invention. Fig. 2 is a section on line 2-2 in Fig. 1. Fig. 3 is a detail view of the foot lever and clutch mechanism. Fig. 4C is a section on line/1&4 in

Fig. 1. Fig. 5 is an enlarged side elevation ofa portion of the chain, showing the lever which is tripped by a projection on said chain. Fig. 6 is a plan of the device shown in Fig. 5. Fig. 7 is an enlarged detail sec- J. MILLnuQ a citizen of the Umted States of America,

tion viewon line 7-7" in Fig. 5. Fig. 8 is a similar section on line 88 in Fig. 6. F g. 9 is a perspective of the lever which is tripped by the chain, and which in turn .trips the foot lever. l lig. 10 is a perspec- Said lever is connected by a red (Z with the lever or arm d upon which the said dog is mounted. Said work-holder carries the cleats and veneer for the blanks, and said staplers secure the binding wires to the same, thus forming the well-known clcat-rcinforced and wire-bound box-blanks. As previously explained, it sometimes happens that the machine will be found, after continuous,operation for some time, to-be driving the staples in the wrong places in the said blank. This is corrected by providing the chain with a projection 0 adapted to trip the lever E, by engaging the cam pro- Said lever has a cam or bevel c which in turn engages the pin 0 on the lever c which latter is pivoted at c ,as clearly shown. v

A link 6 connects the lever c with the catch (2, and the latter engages the foot L vspring f and the dog serves also as a means for preventing back movement of the Work-holder when the feed mechanism is operating. It will be seen that any suitable means can be employed for connecting the said foot lever with the clutch G. In this way the entire machine is automatically stopped every time the chain or work-holder .for feeding the staple Wire is stopped, by means controlled takes place,

plained, and also for the makesa complete revolution. 1f no error or discrepancy has developed in the feed,

thentheop'erator simply presses the foot lever to again start the machine; but if the .blanks are then not in proper position to receive the staples, the operator first read:

justs the work-holder before again starting .work. .Also, the work-holder automatically stops itself. As shown, the automatic stopping device is for use in preventing the driv ing of staples in the wrong place. In other I words, I apply this automatic stopping device to the machine as a part of the general scheme or arrangement for preventing the" .se

.chme, 'ically control exercised by the conveyer is used for driving of staples at times when they are not desired or needed. But it is obvious that this automatic control of the various mechanisms of the machine by the traveling motion of the work may be employed in various ways, or for various .purposes, Without departing from t e spirit of my invention.

As previously explained, the "mechanism automatically motion of the blanks. The other operative portions of the machine are also automatically stopped in the same manner. The purpose of this, as explained, is primarily to prevent the driving of staples in any gaps or spaces left in the Work. For example, it

preventsthe driving of staples between the endsof the blanks, or between the ends of the cleats of the same blank. Of course, and if there were no materials behind the staplers, there would be no necessity for employing this automatic stop action. The machlne, however, is constructed in such"a manner that materials are approaching thev staplers at the'time when the stopping-of the mechanism is required and it 'is'rer the purpose'of properly taking care of the on coming materials that this, automatic stop ping provision is made. interruption of the staple driving operation in order to realize the intent and purpose of the invention, when. the feed mechanism is in position to feed the vmaterials forward. Thus the feed mechanism including the ratchet D is automatically controlled by instrumentalities including means on the endless traveling work holder, said means, for example, and in this particular form the pin 0 projecting laterally from the link belt. The lever E, which is an element of said instrumentalities, moves about its pivot e to stop the machine, as previously expurpose of permitand with this arrangement, there by the feeding In other Words, th'e or use of my invention, consisting of ting-the conveyer to move forward, when necessary, instead of being positively held back by the engagement of the pin a with the engaging portion e of said lever. The said instrumentalities control the operation of the machine, and it follows, therefore, that the conveyer serves in effect and by its forward motion to control itself. Again, are, of course, the staplers B which are automatically controlled (in this case bystopping or rendering them inoperative) by the said conveyer, each stapler being entirely interruptedby the action of the conveyer when the pin a strikes the lever E during the operation ofthe machine. Primarily, it will be seen, this machine is designed for continuous and uninterrupted operation. But with-the said instrumentalities shown and described, whereby the endless conveyer C controls it- If, as well as other elements ofthe mathe continuous operation is automatinterrupted. -In the present case this use, for this feature of myself to any particular unconnected sections of each blank, coinprising "staplers "for "securing the binding Wires to the sheets and cleats, an endless traveling conveyer for presenting the sheetsand cleats to said staplers in superimposed and spacedrelation, nism foractuatin said conveyer, and instrumentahties mc ding means on said con- ,veyer to automatically control the operation ofsaid mechani'sm';
